7 i1 117/ whom, "it may concern ie it known that we, ZACHRIAH and CHARLES'T. LrrcHFmLD. lnited States, residing at Spokane, in the county of Spokane and State of Washington, have invented certain new and useful Improvements in Devices for Oiling the Flanges of Car-Wheels; and we do hereby declare the following to be a full clear, and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

This inventionrelates to devices for oiling the flanges of car wheels and itconsists in the novel construction hereinafter described and claimed.

In the accompanying drawings forming part of this application :Figure 1 is a view in side elevation of aportion of the body of a car mounted on a truck with one of the TISIIER oiling devices applied to the truck. Fig. 2

is a top plan view with parts broken away showing two of the oiling devices mounted on a car truck and applied to the flanges of both of the front wheels. Fig. 3 is a view of the oiling device in side elevation. Fig. 4 is a vertical longitudinal section through Fig. 3. Fig. 5 is a top plan View of the construction shown in Fig. 3. Fig. 6 is a horizontal section through the casing of the valve connected with the oil tank. Fig. 7 is a vertical section through the valve casing. F ig. 8 is a view partly in vertical section of the member carrying the oiling wheel and having a bore connectedwith an oil supply.

Mounted on the frame 10of an ordinary or any preferred car truck is an oiling de vice comprising a bracket member 15 having an upstanding device 16 at one end. which is provided with a vertical bore 17 and has a screw threaded portion 18 at the lower end for connection with a source of located on oil supply.

We employ preferably an oil supply originating from a tank 20 which maybe the car platform and which has connection by means of flexible metallic tubing 21 with the bore 17 at the point 18. Tubing 22 connects with a similar oiling device for the other wheel on the same axle. The tank 2Q may be connected with a valve 25 through which vices under consideration. This valve is shown in Figs. 6 and 7 and the casing has aninlet 5 from the oil tank and outlets 6 and 7 leading to the respective oiling decitizens of the -is held centrally thereon. or

jnects with bore 17,

oil is supplied to the de-' vices. The valve plug hasslots 23 and 23" com'iected by a central passage 24, permitting the flow of oil to either ou tlet, and closing both outlets. Normally the oiling wheel. contacting with the flanges of the car wheel, is held away from the latter by a spring 27, but when it is intended to apply oil to the wheel. air pressure is admitted, and drives the plunger and oiling wheel against the flange of the car wheel, overcoming the action of spring 27.

The oiling wheel is indicated by 30 and is formed in two parts, separated by a washer 30. lVhen the flanges have become worn. the washer may be removed. for the purpose of reducing excessive space between such flanges.

l/Vheel 30 is mounted on a shaft 31 and nearly so. by means of coiled springs 32 and 83 which bear against the sides of the oiling wheel and against members 34 and 35 of a forked member 36, which is in turn carried by body portion 37 operating on tubular member 38. Portion 37 is guided by member 40, and includes a member forming a plunger 41, located as shown with reference to tubular member 38. The bore 42 of the latter conand oil under pressure admitted to said bores acts on the plunger,

for advancing the oiling wheel so that it will contact with the car wheel.

A vertical member 15 a bore 46 leading to a tubular oil supply member 47 discharging at a point between the flanges. of the oiling wheel. supply is regulated by a needle valve 48, and oil is admitted to bore 46 when the plunger and trolley have advanced sufficiently to cause the plunger to clear bore 46.

Air is admitted by pipe 19 to the upper portion of tank 20, from air brake tank 50. Suitable pressure is maintained in tank 20,-corresponding wit the pressure in the train pipe, operated without aflecting the brakes, owing to the small amount of air required for the said devices, compared with the volume of air in tank 20. It will be observed that one of the flanges is provided with,-

The oil and the oiling devices may be of the oilingwheel presents in cross'section her, and a tubular device connected with the reciprocating member and arranged to convey oil to the flange of the'wheel.
